OIL-BURN ER.

Specification of Letters fatenta Patented Aug. 31, 1915.

Application filed September 24, 1913. Serial No. 791,614.

To all whom it may concern:

Be it known that I, ROY CHANCE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to hydrocarbon burners of that type which are adapted to burn crude oil or other liquid-fuel whichis atomized through some suitable medium such as steam or compressed air or the like. The object of the invention is to provide what is commonly known as a hydrocarbon burner in which the atomizingelement and fuel are ejected from the burner in separate streams so that the oil will drop onto the edge of the steam and is thereby atomized.

A common fault with many of the burners of this type is that the pressure of steam backs the oil up in the fuel pipe and thereby prevents proper feed of the oil and it is therefore another object of this invention to avoid this difiiculty.

A further object of the invention will appear as the specification which forms a part of this application is'read in connection with the drawings in which:

Figure 1 is a side elevation; Fig. 2 is a detail front elevation; and, Fig. 3 is a vertical sectional view through the burner.

In the specific embodiment of the invention, as illustrated herein, I provide a substantially cup-shaped burner head 1 having an arcuate fuel opening 2 arranged in the 1 front vertical wall of the head and immedi-' ately below the same, a similarly shaped but smaller opening 3 for the egress of the atomizing medium. The upper end of the cup-shaped head is provided with a threaded plug 1 which may be removed when the oilreceiving chamber 5 needs cleaning. This chamber is formed by a horizontal partition 6 which divides the head into separate compartments 5 and 7, the latter receiving the steam or other atomizing medium and communicating directly with the port 3.

The cup or head 1 is provided with a later ally extending internally threaded nipple 8 which is connected to a coupling member 9 by a pipe section 10 of any suitable type. The coupling 9 is in turn connected to the valve casingll, by a pipe section 12, and

the valve casing 11 is connected to a T'-coupling 13 by a pipe section 14. The coupling 13 has leading thereinto an inlet pipe 15 which communicates with the source of fuel supply, not shown, while the coupling 9 is provided with a laterally extending internally threaded nipple 16 to which is con nected a steam supply pipe 17 having a controlling valve 18 arranged therein. The valve casing 11 is also supplied with a valve 19 which controls the fuel supply of the burner. i

The coupling 9 is provided with a transverse partition 20 which has a centrally threaded aperture adapted to receive the' fuel pipe 21 while the partition 6 is provided with a lug 22 having a. threaded aperture to receive the .opposite end of the pipe. As the partition 20 is located on the far side of the steam inlet of the coupling 9, it will be readily seen that the steam passes around and is entirely separated from the fuel in the pipe 21 and that the fuel is only mixed with the atomizing medium or steam after the exit of both elements from the head 1, thereby preventing any backing of the fuel in the pipe 21 by reason of the pressure of thevsteam, the compartments 5 and 7 being entirely independent of each other.

Having thus described my invention, what I claim is:

A fuel burner comprising a hollow head having horizontally arranged fuel and steam openings spaced from each other in a vertical direction, means positioned between said openings and dividing said head into separate compartments, a coupling, a horizontally arranged fuel supply pipe having its outlet end arranged indirect communication with and in horizontal alinement with said fuel openings, a steam supply pipe connected at another end of the coupling, means for connecting the coupling to the head, a partition in the coupling arranged between the connection with the steam supply pipe and the fuel supply pipe, and a fuel pipe passing through and connected to the partition and to the means for dividing the head, said fuel pipe communicating with one compartment in the head and with the coupling beyond the partition. In testimony whereof I afiiX my signature in presence of two witnesses.
